Patent CA-2172468-C (CA)
Inventor: BUCHER DAVID HOFFER
IPC: A01B35/22
Filed: 1996-03-22
Granted: 1998-11-03
Abstract: Knock-on sweep mounting structure includes a combination of first and second tapers, and mating notch structure in the sweep connecting portion and in the mounting structure on the shank, to provide easy installation and prevent sweep loss. The notch structure facilitates easy connection of the sweep on the mounting structure by rotational movement of the sweep at a single narrowed attaching location between the tapers. Once on the mounting structure, the sweep can slide along the shank. By forcing the sweep upwardly, the sweep is wedge-locked in the field-working position on the first taper.  The second taper, opposite in direction from the first taper, fits against the naturally occurring shape of the bottom of the sweep connecting portion to retain the sweep on the shank if the sweep is dislodged from the first taper.  The combination of tapers with the notch structure located therebetween substantially reduces the possibility of a sweep accidentally falling off the shank.
